The conversations you're avoiding are costing you.

You're avoiding hard conversations. Meetings that used to be productive now feel tense. You're second-guessing each other's decisions. Maybe you've stopped communicating altogether.

The problem isn't that you disagree — it's that you've lost the ability to disagree well.

Startup operator meets relationship scientist.

Jason Shen brings a rare combination: the hard-won experience of a startup operator and the evidence-based tools of a relationship scientist. He's been where you are.

50+ founders coached since 2020

After his own painful cofounder breakup nearly ended his company, Jason trained with the Gottman Institute — the gold standard in relationship science — and developed a methodology specifically for startup partnerships. That difficult experience became the foundation for helping others.

Most coaching treats symptoms. This program works on the system.

The methodology combines Gottman-based relationship science with deep startup context. It's not therapy. It's not mediation. It's a structured program for founders who are ready to do the work — and get back to building together.

The Four Phases of Cofounder Conflict

Phase 1
Drift

You stop sharing what you're really thinking. Small annoyances accumulate.

Early signs include fewer 1:1 conversations, growing internal frustration, and a preference for async over face-to-face discussion.
Phase 2
Gridlock

Key decisions stall. Conversations become circular.

You revisit the same arguments without resolution. Strategic alignment breaks down, and team members start to notice the tension.
Phase 3
Crisis

Trust breaks down. One or both founders consider leaving.

The partnership feels adversarial. Board members or investors may be drawn in. The company's survival feels uncertain.
Phase 4
Resolution or Dissolution

With intervention, most partnerships can be repaired.

A structured process helps you either rebuild the partnership on stronger ground or navigate a respectful separation that protects the company.

Most teams reach out during Phase 2 or 3. The earlier you start, the more options you have.

"The Gottman-based work on affirming positive needs gave us a framework we still use every week. Jason didn't just help us resolve our conflict — he gave us tools to prevent the next one."
